2022 Grand Design Solitude

• Cracks in the Pin Box: A reputable RV dealer/shop has identified significant cracks in the pin box, indicating a serious structural compromise. • Slide-out failures: The GIBs on the slide-outs have broken, causing them to extend while the RV is in transport on highways. • Cargo door malfunctions: Cargo doors are repeatedly popping open during highway travel. • Main entry door instability: The front door and screen are not operating correctly, preventing proper closure and causing the door to open unexpectedly during transport. • Structural fastener failure: Screws and bolts are detaching from the unit during transport. • Front cap detachment: The front cap is popping open at the fifth-wheel hitch area and exhibiting significant sway during transport. These issues collectively indicate a severe underlying problem with the structural integrity and frame of the 2022 Grand Design Solitude, creating hazardous conditions for both the occupants and other road users. I urge NHTSA to investigate these defects thoroughly to prevent potential accidents and ensure consumer safety.

We bought our 2022 Grand Design Solitude 346FLS-R in March 2023. We have had numerous safety issues and concerns, and currently don’t feel safe towing it. 1. External locked compartments and entry door open while traveling. Risks: distraction, collision (passing vehicle or objects), quick maneuvering (to side of road), contents ejected onto road/vehicles. Resolution: Shops have tried to fix, but problem continued. I placed some screws to extend the latch plates. Concerned this is a “frame flex” issue, along with our floor separation, sheared screws, saw dust, etc. 2. Three axle/suspension failures. In 3/2024 and 12/2024, sudden/extreme tire wear was noted due to failed suspension (broken leaf springs, cracked equalizers). In 8/2025, while driving on [XXX], an entire wheel disappeared. We called the MI highway department afterwards and they had no reports of accidents or debris due to the wheel. Roadside assistance got us to a local repair shop that found the 3 other tires were badly worn/damaged, rear passenger side leaf spring cracked (3rd time), and remaining brakes "fell apart in chunks". The technician diagnosed a bad spindle. As the work was completed, the shop owner stated "I don't think your suspension is fit for this rig. It already appears max'd out." Risks: The entire wheel flying off on the highway could have easily killed someone. Suspension failure while rolling could lead to tire blowouts/catastrophic damages/major accident. Resolution: Suspension repairs made/tires replaced. Recently stopped in at Grand Design in Elkhart, IN to speak with the Customer Service Director about these safety issues. The GD shop is booked until December, but a frame and suspension inspection at a GD dealer was authorized. CW Direct in Elkhart completed the inspection, found a frame crack and assessed the 7K suspension as insufficient. Still no resolution and we now have not been able to live in our home for over two weeks. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2022 Grand Design Solitude. The contact stated while driving at an undisclosed speed, the doors unlatched and opened. The contact stated that the bolts were missing, the furniture moved, and the walls shifted. While driving at an undisclosed speed, the RV failed to drive in a straight line. There were no warning lights illuminated. The vehicle was taken to the local dealer where it was diagnosed with fractured slides and failure to the frame. There was an unknown diagnosis related to the suspension. The vehicle was repaired to the original specifications, but the failure recurred. The manufacturer was not contacted. The failure mileage was unknown.

Exsessive frame flex/failure, Structural and Mechanical Issues · Cracked and separating frame. · King pin alignment is visibly off when hitched, greatly reducing maneuverability. We can no longer safely jackknife the trailer. · Front cap is separating and leaking, allowing water intrusion into the RV – a serious concern for mold growth. · Closet wall separation. · Basement doors pulling away and separating. · Sagging kitchen floor causing a slide to become non-operational (required emergency assistance from a mobile RV technician). · Missing rollers under the kitchen slide. · Screws consistently fall out throughout both front and rear basement compartments. Main doors and cargo doors opening during travel

Our frame on our 2022 Grand Design Solitude S Class 3740BH has failed. While towing this RV 5th wheel trailer, we have observed signs of frame flex/failure and now it has been verified by RV tech Justin Douglas of TBD RV Repair out of Denver, IA 319-883-6030. Items to note: Our hitch inbox appears to rise and fall several inches during transport. The front cargo doors and side entrance door have opened during transport after being secured. Several pieces of moulding have “pulled” out from shifting along the front trim of the trailer. The afore mentioned left and right sidewalls appear to shift during transport resulting in pulled screws that support the bedroom floor connected to the sidewall. The roof membrane has separated at the front cap from shifting back and forth. We believe they’re maybe be structural damage to the roof and front chin cone as well under the membrane but we have yet to open the roof to protect the rest of the trailer from rain. Cabinetry in the front bedroom has shifted causing separation of the shelves. The thin staples keeping the particle board have fallen back into the front cone. We re-secured them so we could use the closet without items falling into unaccessible parts of the structure. The bedroom and master bath floor squeak and rise and fall (move) when walking on them The bedroom door has also gotten stuck closed after transport due to shifting. The right side leaf spring compensator (CRE device) was cracked from what was believed to be from lateral shifting and was replaced. No lamps or warning messages were applicable for this problem. The police have not been involved at this time nor any insurance as of yet. We feel that if these items are not immediately corrected by Grand Design, this may result in a safety risk on the road.

While towing on I-75 at 65 MPH, the driver's side front storage doors came open. These doors had been shut, locked, and checked before departing. They were secured again and remained closed at a lower speed. Examination revealed two design flaws. First, they are side-opening overlapping doors. With an overlapping (rearward) door facing forward, this allows the slipstream to enter the gap putting strain on the two retaining locks. The second is on the two cabinet cam locks for the forward door. The throws for both are short with the upper barely making contact with the frame of the opening. vibration causes this one to come loose opening the gap for even more slipstream penetration. Solution reorient doors so overlapping is facing rearward, and put longer throws on cam latches. I replaced the short one with a longer one that had to be molded to fit, the forward door is much more secure now. This problem has been reported by other owners of this model 390RK on Facebook.
